This invention relates to improvements'in elevators yand more particularly to such devicesas are employed in the loading and unloading of ship cargoes. .'Animportant 'fea- .1155, tureof the invention is that the elevator proper: may be operated `vertically inl the usual manner of elevators, and that means.

are provided which allows one end of the elevator floor to move vertically,`,and means "for 'm restrainingtheopposite end sothat a ramp load to'mov'edown from' the dock to the ships deck on such a steep angle. `'lhisfcondition would occur for instance if the 'tidewas very flowy'ln such `cases a more gradual angle may fbe given to' the ramp by yforming a double ramp, 'asj'ust indicated; Another' very important feat-ure of the invention is the peculiarconstruction of the dock apron,-which consists v'mainly'in hinging the apron'to the f outer edgeV ofthe elevator "floor so that theV freefend of the apron will accommodate itself .to varying conditions ofthe tide'inthe usual manner, and also-.the provision of. means 4.which allows forflatera'l movement ofi'. the

shipwith respect to the'docl without injuryl i. v

An apron 33 which can rest on the ship 20,

thereby forming a continuous incline from platform 4 islpivotallyV supportedsothat `when "thepship is `being ,loadedjit may be striking the apron. y

Referring more particularly to `llig. ,3,

apron 33 is rotatably mounted on a shalftf- Y which is provided withguidebloclgs L 36 which l rounded; holeI asi-ndicated fatI 39 V@The apron mounted only-at the centerofthe shaftl by .the-bearing block BS whichhas alargeA and is prevented` from moving along thef shaft' by blocks-#l fixed to theshaft '35, .A'bloek41is Afastenedfrigiidly yto the gapron, and fsupports a spring fwhielrbears ,against thegsliafft 35 withiits outernendsil.
